Dataset accompanying "Anaerobic sulphide removal involves an intricate interplay between biomass, biosulphur, and dissolved compounds"

In anaerobic conditions, haloalkaline sulphide oxidising bacteria (SOB) are able to spatially separate sulphide removal and oxygen consumption, thereby shuttling sulphide from sulphidic to aerobic environments. Previous investigations on sulphide shuttling was performed on biomass isolated from reactor effluent. To see whether the other constituents of reactor effluent also play a role in sulphide shuttling the anaerobic sulphide removal behaviour of isolated effluent fractions (biomass, biosulphur, and the dissolved fraction) of different reactor types were investigated in batch. In anaerobic conditions, sulphide concentration as well as oxygen reduction potential (ORP) were measured during for minutes after sulphide addition. Using this dataset, the related publication shows biomass, biosulphur, and the dissolved fraction all interact and contribute to anaerobic sulphide removal observed in the biodesulphurisation process.
